Yes copies were made. The files were downloaded, one way or another (even as a hash, or whatever digital asset they claim to translate them into) then fed to their machines.
If I go into a Ford plant, take pictures of their equipment, then use those to make my own machines, it’s still IP theft, even if I didn’t walk out with the machine.
Make all the excuses you want, you’re supporting the theft of other people’s life’s work then trying to claim it’s ethical.
By that logic I can sell anything I download from the web while also claiming credit for it, right?
Downloading to view != downloading to fuel my business.
